Expertise in the Spring framework is highly sought after and will help open up a lot of job opportunities for you. Here you will get familiar with Spring 5 and Spring Boot 2 to add dependency injection into your applications.

You will start with the basics of Spring like dependency injection, auto-wiring, and constructor injection. After the basics are out of the way you’ll move onto Spring Boot, Spring MVC, Spring JDBC, and Spring Data JPA.

Lastly, you’ll delve into Spring’s support for AOP, unit testing, and the MVC architecture. By the end of this course you will have a wide set of tools to work with to create applications that have dependency injection and inversion of control.

The Complete Guide to Spring 5 and Spring Boot 2

In this lesson,  we will create an endpoint for the REST API which creates a new player and adds it to the database.

The REST client will send a POST request to `/players`. The body of the request contains the JSON data for a player. Since this is a new player, the client will not pass the ID (primary key). The backend system will generate the key for the new record.

The REST service will convert JSON data to POJO and add it to the database. The primary key of the added player is automatically generated by Hibernate, which is the default ORM used by Spring Data JPA. The response to the client is an echo of the player details along with the newly generated ID value.
